s6 itknownthat I FRANK W. MAzsioK, a citizen ofthe United States, and resident of North .Milwaukee, in the county of Milwaukee and State of Wisconsin, .have invented" certa-in new and useful Improvements in Acetylene Generators; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

My invention refers to carbide gas-igenerators, and has for its object to provide a simple, economical and effective feed mechm nism for such, generators. The specific ob ject of the inventionis to provide a feed mechanism wherein tooth gearingv is dispensed with, andthe parts are arranged to be so controlled-that should the generator bellfail to respond when a charge of carbide is delivered, due to the weakness in its strength, an auxiliary charge will be de'' livered to reinforce the first charge, whereby the desired quantity of gas is generated to lift the bell.

With the above and other minor objects in view, the invention consists in certain' peculiarities of construction and combination of parts as arehereinaf-ter set forth, with reference to the accompanying drawings and subsequently claimed.

In the drawings,

Figure 1 represents a sectional elevation of a generator embodying the features of my invention, and

Figure 2 is a cross section on the line 22 of Figure 1 illustrating more particularly the details of the valve mechanism.

Figure 3 is a section taken on line 33 of Figure 1.

Referringby characters to the drawings, 1 represents the tank, the lower portion of which constitutes a well adapted to receive the proper quantity of water, and communieating with which is a clean-out pipe 2. The tank. is provided with the standard bell 3, having suitable guides 3, it being understood that the bell is adapted to rise and fall in the usual manner. Its lower edge is submerged in a water seal 4, which seal is formed by a jacket 5 that is secured at its bottom to the side walls of the tank. A service pipe 6 extends through the jacket wall 5 and communicates with the interior of the bell, the outer end of which pipe is adapted to be coupled to a suitable supply connection. T he top wall of the bell is pro- Specification of Lettersfatent 1922.

strap- 12f that is secured; to cylinder 9 whereby all of these parts are self eontained.

Thebell is provided withend walls 13 which form journals for trunnions 14 of a cylindrical valve 15, Thisyalve is formedwith a main port '16, which normally communicates withthe throat 10 and is so positioned that its "delivering mouth is closedlbythe cylindrical shelllQ. A bypass or auxiliary port 117 communicates with the main port lGand terminates at the outer wall of the valve shell a predetermineddistance from The throat 10 ofthe the intake mouth ofthe mainport, this auiiiliary 'po'rt being also normally closed by the shell. The port 16 is of such areaas to hold the normal quantity of carbide, which is of standard strength. Hence, when the valve is rotated below the lower edge of the shell, this charge of carbide will be delivered to the water, whereby gas is generated. If, however, the carbide is not of sufficient strength to generate a volume of gas for lifting the bell, the mechanism is arranged to automatically shift the valve, still further, in its direction of discharge, whereby the restricted auxiliary port will come in communication with the throat 10 and deliver a small continuous stream of carbide to the water until such 1311118 as SllfilClGIlll gas 1S generated to lift the bell. Themeans for autoniatically actuating the cylindrical valve comprises an arm 18 which is secured to one of the valve trunnions and is connected by a link 19 to the rocker arm 20, which rocker arm is fulcrumed upon a bracket secured to the apron 9 of the hopper 9. The outer end of the rocker arm 20 is connected to a reciprocative plunger rod 21, which projects above the hopper and is arranged to be engaged by the bell when said bell reaches a low position, due to the gas contained therein having been reduced in volume. The

arm 18 has adjustably secured to itsouter end a coil spring 22, the opposite end of said spring bein connected to one of the bracket elements. ihis spring serves to hold the plunger rod 21 upwardly and to also'maintain the valve port 1 6 in its normal posi-. tion communicating with the throat 10, and. the parts are held in register'ibymeans ofthe spring power which tends to rotate the valve until such time as a stop dog23' carried by the valve comes in contact with the lower'edge of the shell 12,"as shown in Figure 1.

Attention is also directed to the factthat when, the spring acts to restore the valve -to its normalposition after it has discharged.

Q i Y jWhile I have shown and described the novel features of my invention minutely as to detaih'it is understood [that I may-vary the structural features so'described within the scope of the claims. (Itwill' also benoted' that while I have shown a springi for actuat ing'the valve arm 1n one direction, I may in some instances employ aweight for accompli'shing the same results.
